Doctors believe that lasers may be the secret to curing some of the world’s most tragic diseases.

Lasers could prove to be the key in eliminating brain diseases like Alzheimer’s and Parkinson’s. New findings from researchers at Chalmers University of Technology and the Polish Wroclaw University of Technology have raised hopes that doctors may one day be able to cure the ailments without needing to touch surrounding brain tissue. Such a technique could also replace the chemical-based treatments used to treat amyloid protein aggregates today, which involve toxic components that can put patients at risk. The researchers discovered that it was possible to distinguish aggregations of the proteins thought to cause brain disease with the help of multi-photon lasers.
